* Looking past Stone’s intricate play-by-play to the wider context, it’s hard not to view Uber and Airbnb as a new iteration of the upheaval and consolidation Taplin describes. The difference is that while Amazon, Facebook, and Google tighten their control over the entertainment we consume, the personal details we share, and the information we uncover, Uber and Airbnb want to stake a claim on how we move through the material world. Kelly describes this state of affairs as a new form of socialism untethered from the state, “designed to heighten individual autonomy and thwart centralization.” To me, it sounds more like Sigma Iotia II, the gangster-themed planet in the Star Trek episode “A Piece of the Action.” It’s a world that, though torn apart by gang wars as the Enterprise arrives, is made to run smoothly when Captain Kirk inserts himself and his superior phaser technology into the conflict on behalf of the Federation, declares himself the victor, and then withdraws to allow the society to rule itself … as long as the Federation gets its cut. Kirk promises that money would be reinvested back into the planet — but that works mainly because the post-scarcity Federation can afford to treat Sigma Iotia II as an extended, world-sized experiment in developmental sociology.
